Ya its great of piece of work. but it looks more like a science project than a working machine. I know about lots of experiments going on but i hope this one is real. Still a good thing to show to kids, they need things like that to learn.
great for people on wheels who don't get much of time for charging. good for people on beach too. Not good for me. and definitely not good for miners. Might be good for tarzan, he need new technologies in the wild. lol.
